Sourdough Starter Ritual

I started a sourdough starter 6 months ago. The daily feeding, equal parts flour and water mixed into the jar and left on the counter, has become a habit that anchors my morning in a way I didn't anticipate. The starter is a living culture of wild yeast and bacteria. It smells like tangy yogurt when healthy and like acetone when hungry. Learning to read those smells took about 2 weeks. Fermentation is visible: the surface bubbles, volume doubles in 4-6 hours, and texture shifts from thick paste to airy mousse. Once a week I bake with it. The bread has a complexity commercial yeast can't produce: slight sourness in the crumb, a darker crust, an open texture with irregular holes.
